Therear wall of the container leryettrsetlon, the wicks are kept constantly j is provided with a rectangular opening, while; saturated. Therefore. ai'r passing through the the fro twall is providedwlth a slnular opening openings l2 and l 3 in the casing must pass 55 through and around the saturated wicks because a sufficient number of wicks are provided to substantiallyextend across the length of the openings. Thus, it will be seen that this air passing through and around the wicks is cooled.

For supporting the wicks and retaining them in a vertical position, a spring coil 23 is provided for each wick. The upper end of each coil is secured to one of the couplings l8, while the lower endof the coil is 'secured'to one of the cou-' plings IS. The coils may be formed of any suitable material, but it is preferable to form them of wire which is rust proof and capableof considerable flexibility Without losing the shape into which it is formed. The ends of the coils may be connected or attached to the couplings by weld-1 ing or in any other suitable manner.

The coils are tensioned sufficiently to prevent sagging, but if desired all or part of the coils may be extended and thus compressed endwise when secured between the couplings. The coils are disposed side by side, or parallel, and each coil is spaced from those on each side thereof. It is obvious that the number of coils may vary. 7 One of the wicks II, which is made of moisture exuding materiaLsuch asfelt fabric or the like, isinserted into each coil. The wicks are preferably of a smaller diameter than the interior of the coils so that when they are moistened and swell, they will not protrude between theturns of the coils or buckle betweenthe couplings.

From the foregoing it is obvious. thatair passing through the. openings I2 and I3 in'the casing must pass through and around the wickswhich are kept s'aturated-bylcapillary attraction. The wicks serve to cool the air as it passestherethrough. If desired, adjustable louvers 24 may be mounted in the opening l3, whereby the amount of air passing through the casing may be readily controlled. It is pointed out that the coilsare merely means for supporting the wicks to hold them in position, and any suitable bracing means may be employed. v Since the device is mounted in a singlecasing, it comprises a portable unit whichmay be readily moved froinplace to place. In Figure 2, I have shown the casing mounted forwardly of an electricfan 25, wherebyaconstant draft of .air is forced through the casing. The fan is not an .essential, part of the apparatus, for the casing could be placed before an open window or in any other suitable place. 7

It is brought out that the arrangement of the unit is such that its action is entirely automatic.

- There areno adjustments to be made and all that is necessary is to occasionally fillthe Water, tanks l4 and IS. The hinged top ll provides for the easy removal and I insertion of the' upp'er tank I4, aswell as the refilling thereof. The lower tank may be readily refilled through the opening l2 in the rear wall thereof. 50 long as the tanks contain water, capillary-attraction will keep the wicks saturated and so long as the wicks are kept saturated, air passing through the casing will be cooled. f 1 o and turnedback thereover,
